DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: In many science areas where  datasets  need to be transferred or shared, rapid growth in dataset size, coupled with lack of increase in wide area data transfer bandwidth, is making it extremely hard for scientists to analyze the data. This paper addresses the current limitations by developing SDQuery DSI, a GridFTP plug-in which supports flexible server-side data subsetting over HDF5 and NetCDF data formats. The GridFTP server is able to dynamically load this tool to download any data subset. Different queries types (query over dimensions, coordinates  and values) are supported by our tool. A number of optimizations for improving indexing (parallel indexing), data subsetting (performance model) and data transfer (parallel streaming)  are also applied. We have extensively evaluated our implementation. We compared our GridFTP SDQuery DSI with GridFTP default File DSI and showed that in different network environments, our method can achieve better efficiency in almost all cases.
